Plethora of information in no certain order.

In mid September I combined a couple hives and tried a split. The split failed within a week which included a new queen. It was worth a try but I think the percentages are low that it would work as late as it is in the season.
The following week Andrew Joseph came to inspect hives for myself and a couple other association members. Started treating for varroa and beetles at this time. (Sept 22nd-25th)
Before treating I removed all honey supers and frames to be harvested this year.
In the last couple weeks I've started to supplement feed with sugar water mixed with after honey from bees wax preparation.
Today decided to reseed hives at the someplace. Unfortunately had my first CCD hive. No bees and almost all robbed out. I did notice about three days ago some flies at the entrance so that should have been a clue.
Here's some pics/video.
